FIR Filtering Based Image Stabilization Mechanism for Mobile Video Appliances.

This paper proposes a new image stabilization mechanism based on filtering of absolute frame positions for mobile video appliances. The proposed mechanism removes undesired motion effects in real-time, while preserving desired gross camera displacements. The well known finite impulse response (FIR) filter is adopted for the filtering. The proposed mechanism provides the filtered position and velocity that have good inherent properties. It is shown that the filtered position is not affected by the constant velocity. It is also shown that the filtered velocity is separated from the position. Via computer simulations, the performance of the proposed mechanism is shown to be superior to the existing Kalman filtering based mechanism. [ABSTRACT FROM AUTHOR]
